Display Tile Alignment Mechanism for Front-Accessible Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for aligning and fastening display tiles in tiled displays require extensive manipulation, which can damage fragile display elements and necessitate high precision, especially when seams are smaller than the fastening means, and there is no reliable solution for accessing fastening mechanisms from the front of the display.
Innovation Solution
An intermediary support structure with a linear or rotational actuator that moves display tiles along a predetermined path, allowing for safe and reliable installation by maintaining a safe distance during alignment and enabling fastening from the backside, reducing the risk of damage and precision requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If extensive manipulation is used to align and fasten display tiles, then alignment precision can be achieved, but display elements are damaged due to shocks and contact with fragile components
Solution Approach 1:
The patent introduces an intermediary support structure that acts as a mediator between the display tile and the mounting surface. This support structure provides a stable platform for alignment operations without requiring direct contact with fragile display elements, thereby achieving precise alignment while preventing damage to LEDs and other sensitive components.
Solution Approach 2:
The system separates the alignment and fastening functions into distinct stages. The support structure enables preliminary alignment operations to be performed on the tile before it is permanently mounted, allowing precision work to be done on a stable, accessible platform rather than attempting to manipulate the fragile tile itself in its final position.
2Ease of operation
If fastening means are positioned to access from the front of the display, then installation is simplified and reliable, but seam size must be larger than the fastening means
Solution Approach 1:
The patent resolves this contradiction by changing the dimension of access - fastening means are positioned to be accessible from the front of the display (horizontal/vertical plane), but they actually attach to the support structure that is mounted on the backside of the tile. This dimensional shift allows operators to access fasteners from the front without requiring large seams, as the fastening action occurs at the rear interface between the support structure and mounting surface.
3Device complexity
If manual alignment methods are used, then device complexity is reduced, but productivity is lowered due to extensive manipulation time
Solution Approach 1:
The support structure enables preliminary positioning and alignment operations to be performed before the tile is permanently fixed in place. This preliminary action allows workers to perform alignment adjustments on a stable, accessible platform without the time pressure of final positioning, thereby reducing the total manipulation time while maintaining simple mechanical alignment methods rather than requiring complex automated systems.

AI summary
An intermediary support structure that includes a linear or rotational actuator to move the single display tile from a first position in a first plane along a predetermined path to a second position in the first plane. The first position is a loading position of the single display tile in the tiled display and the second position is a position in which the single display tile lies when installed in its operative position in the tiled display. When the single display tile is located in the first position, there is a distance between the loading position and the operative position, the linear or rotational actuator is configured so that the distance becomes smaller as the single display tile is moved along the predetermined path towards the second position. The linear or rotational actuator is accessible and remains accessible until an adjacent display tile is covering an access to the actuator.
